How to achieve dynamic filter in django
In my frontend, I have three kinds of filter and when user selects selects those and click on filter then I need to update the results. The problem is user may select any one or two or all the three filters combinedly. But my code just filters only one condition: Here is my code: filter1 = request.POST.getlist("filter1") //Every filters are in arrays filter2 = request.POST.getlist("filter2") //Every filters are in arrays filter3 = request.POST.getlist("filter3") //Every filters are in arrays data = Data.objects.filter(is_approved=True, published=True) //This the model to be filtered if len(filter1) > 0: data = data.filter(intakes__contains=filter1) if len(filter2) > 0: data = data.filter(elevel__contains=filter2) if len(filter3) > 0: data = data.filter(country__in=filter3) How to make this dynamic ? Like it should filter based on more than one selections. Please help -

Best way to create a custom view and serializer output grouping the results based on a foreying key filter
I am doing some work around the Django rest framework to get an custom output that matches with the charts that i am using. But i am trying to figure out how can i group the serializer by the categories, that are a foreying key field. I don`t know if that would be nice to use filters in the get_query, or if there is a better solution, as there are many categories. Thats what i have made so far: my models: class Category(models.Model): name = models.CharField(max_length=255) slug = models.SlugField(max_length=255, unique=True) class Asset(models.Model): category = models.ForeignKey(Category, related_name='categories', on_delete=models.CASCADE) ticker = models.CharField(max_length=255, unique=True) class PortfolioAsset(models.Model): asset = models.ForeignKey(Asset, on_delete=models.CASCADE) total_today_brl = models.FloatField() Here is the serializer: class PortfolioAssetSerializer(serializers.ModelSerializer): category = serializers.CharField(source='asset.category.name') x = serializers.CharField(source='ticker') y = serializers.FloatField(source='total_cost_brl') class Meta: model = models.PortfolioAsset fields = ( 'category', 'x', 'y', ) And here the view: class PortfolioAssetList(generics.ListAPIView): serializer_class = serializers.PortfolioAssetSerializer def get_queryset(self): return models.PortfolioAsset.objects.all() # return models.PortfolioAsset.objects.filter(asset__category__name="Fundos Imobiliários") def list(self, request, *args, **kwargs): response = super(PortfolioAssetList, self).list(request, *args, **kwargs) response.data = { "name": "category", "data": response.data } return response The output thath i could get with that code was that one: { "name": "category", "data": [ { "category": "category 1", "x": "ASSET1", "y": 10373.4 … -
How to duplicate Django models with OneToOneField relations
Start with the following models using django==3.2.12: from django.db import models class Root(models.Model): pass class Leaf(models.Model): root = models.OneToOneField(Root, related_name='leaf_data', on_delete=models.CASCADE) Run the following in the shell: >>> from myapp.models import Root, Leaf >>> root = Root() >>> root.save() >>> leaf = Leaf(root=root) >>> leaf.save() >>> root <Root: Root object (1)> >>> leaf <Leaf: Leaf object (1)> >>> new_root = Root() >>> new_root.save() >>> new_root <Root: Root object (2)> >>> root.leaf_data <Leaf: Leaf object (1)> >>> leaf = root.leaf_data >>> leaf.pk = None >>> leaf.root = new_root >>> leaf.save() >>> leaf.root <Root: Root object (2)> >>> root.leaf_data <Leaf: Leaf object (2)> Why does the original root.leaf_data reference change? I would expect that by setting leaf.pk = None and leaf.root = new_root that the original root/leaf structure would remain intact. I'm trying to create a full duplicate from the original. -

Django - Upload multiple files using filepaths provided in an excel file
Hope everyone is doing well. I'm trying to figure out how I can upload files from a file path provided in an excel file. Basically I'm allowing the user to upload multiple documents at once but the document name has to be different as such I'm using an excel upload file. How would I go about: Checking if the file exists (I.E File path is accurate) Getting the file to save to model Currently for 1 I'm using: error_list = [] i = 1 for record in df_records: my_file = Path(record['file_path']) try: my_abs_path = my_file.resolve(strict=True) except FileNotFoundError: error_list.append(f"Error in row: {i}, file path incorrect or file does not exists") I'm still looking for a solution, if I find it before someone answers I will post the answer. :) Thanks in advance, Tom -
Wrong table names format - Django
I'm having an issue with the table names format of my Django project. Here is a sample of a model I have: class WalletHistory(models.Model): wallet = models.ForeignKey(Wallet, on_delete=models.CASCADE, related_name='wallet_history') free_amount = AmountField(default=None, blank=True, null=True) locked_amount = AmountField(default=None, blank=True, null=True) flexible_amount = AmountField(default=None, blank=True, null=True) date_created = models.DateTimeField(auto_now_add=True, blank=True) The app associated with this model is called core so the table name is supposed to be core_wallet_history. But Django names my table core_wallethistory instead: it doesn't split the class names with underscore. I've changed nothing in the Django settings. -

Setup React, Python and Neo4j in Docker
I'm trying to set up a Docker container running React on the frontend, Django on the backend and Neo4j as the database. At the moment all three components are running correctly, but I just can't get Django to connect to the Neo4j database. I've probably read all the tutorials on the internet and tried all the things but it always comes up with some error and the database is unreachable or denies access. I have also worked through this tutorial and created the models accordingly. However, I always get an error when I run "python manage.py install_labels". As it looks I either can't connect to the database or the request is rejected. Has anyone of you ever set up a similar environment or can help me? Maybe Django is just not that suitable for it .... Basically I just want a React frontend and a Python backend working with a Neo4j database. And the whole thing please in a Docker image. Are there any better alternatives for the backend?

How do I deploy a monolithic Django/React app?
I’m trying to find a way to deploy my app that uses Django on the backend and React front end, and also uses the Spotify API. The project is based on this tutorial by Tech With Tim I’ve seen some tutorials that suggest splitting it up and deploying them as two apps, where the backend proxies API requests to the backend as necessary, however since my React app is served with Django, I don’t think this method is conducive to how my app is set up. I've tried to deploy with Heroku but I haven't been successful. I'm not sure if its relevant, but I used webpack. Here's my folder structure: Any help? I’d be much obliged. -
Adding instance name of FK to upload_to folder

Django updating value in a loop
Please keep in mind, that I just started learning Django and MySQL. I created a script that can read my transactions from my bank statements and added them to a MySQL table which contains the following fields: id,amount,creditordebit,bookingdate ,partner ,category I'm trying to create an interactive site to loop over the newly added data and update the category field based on the transaction type/partner. I want to loop over them one by one and categorize them using forms.ChoiceField. So far I have created the forms.py and the forms.ChoiceField and choices list, but I am having trouble creating a view and template for this. I have tried to use the QuerySet iterate() but I could not get the next item by id, it jumped straight to the last id. Is this even possible with Django only or do I need to also include some JavaScript? Thanks! -
Django Cors Allow Access-Control-Allow-Headers
I'm trying to make a simple API using Django. I have setup a django server, and then on my own html file I send requests using $.getJSON. So far it's been working using the django cors headers package. Now I've been trying to send a request header to my django server, but I'm getting this error in the Chrome console: Access to XMLHttpRequest at 'http://127.0.0.1:8000/api/?q=example+query' from origin 'http://localhost:63342' has been blocked by CORS policy: Request header field Example-Header is not allowed by Access-Control-Allow-Headers in preflight response. I'm not sure what's the problem, I have django-cors setup correctly and I am able to make requests, I'm just not allowed to set request headers. Setup: INSTALLED_APPS = [ ... 'corsheaders', ] MIDDLEWARE = [ ... 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', ... ] CORS_ALLOWED_ORIGINS = [ "http://localhost:63342" ] <script> $.ajaxSetup({ beforeSend: function(request) { request.setRequestHeader("Example-Header", 'Example-Value'); }, }); $.getJSON("http://127.0.0.1:8000/api/?q=example+query", function (data) { console.log(data); }); </script> @cache_page(60 * 60 * 24 * 7) def ExampleAPI(request): if request.method == 'GET': print(request.headers['Example-Header']) # Print Header Value print(request.GET.get('q')) # Print URL Query Parameter Value return JsonResponse([{"Example-Response": "Example-Response-Value"}], safe=False) So what am I doing wrong? Does django-cors not support this? I tried reading the docs but I could not find anything. Thanks. -
